TJ. Glycolysis breaks glucose (a six-carbon-molecule) down into pyruvate (a three-carbon molecule). In eukaryotes, pyruvate moves into the mitochondria. It is converted into acetyl-CoA by decarboxylation and enters the citric acid cycle.
Oxidative Decarboxylation of pyruvate: in mitochondria; pyruvate formed during glycolysis is transported from cytoplasm into mitochondrial matrix where it is decarboxylated (loses a CO2) & the acetyl group that remains is transferred to coenzyme A to form acetyl CoA; in the process, NAD+ is reduced to NADH
The Krebs Cycle is the central metabolic pathway in all aerobic organisms. The cycle is a series of eight reactions that occur in the mitochondrion. These reactions take a two carbon molecule (acetate) and completely oxidize it to carbon dioxide. The cycle is summarized in the following chemical equation: acetyl CoA + 3 NAD + FAD + ADP + HPO4-2 ---------------> 2 CO2 + CoA + 3 NADH+ + FADH+ + ATP

Here is a great cell respiration resource for AP Biology. It's a 2-page handout with cards that sequence glycolysis, pyruvate conversion to Acetyl CoA, Krebs Cycle, Electron Transport Chain, and Chemiosmosis. Students take the events of cell respiration and add of breathing, eating, making ATP, and exhaling carbon dioxide.
